AbstractThe vermifiltration (VF) technology has gained significant attention as a green alternative for remediating domestic and industrial wastewater over the last few decades. Of late, the implementation of various modifications to the orthodox VF technology, including tweaks in the design and operation of the vermifilters, has been portrayed in the ...

AbstractIn this study, we investigated the performance and elucidated the synergistic effects of microalgae–fungi symbionts co‐cultured with 10−7 and 10−9 mol L−1 of GR24 and supplemented with endophytic bacteria, multi‐walled carbon nanotubes (MWCNTs) or vitamin B12 (VB12), on nutrient removal and biogas upgrading.

In this paper the effect of different SRT on the performances of an ultrafiltration pilot MBR operating with real wastewaters was tested to analyse both the ability of the system to remove nutrients and micropollutants and the possible decrease in waste sludge production.

Polycyclic aromatic hydrocarbon (PAHs) are persistent organic pollutants and pose high risk in aquatic environment. The utilization of biochar is a strategy for PAHs-contaminated remediation but is challenging due to the adsorption saturation and reoccurrence of PAHs desorbed back into water. In this study, iron (Fe) and manganese (Mn) were provided as

Performance of Pilot-scale Constructed Floating Wetlands in the Removal of Nutrients and Pesticides
Water Resources Management, 2021Aiming to evaluate the efficacy of constructed floating wetlands (CFW) in removing agrochemicals (nutrients and pesticides), a series of experiments were run continuously for a 16-week period in pilot-scale CFW systems to study the effect of two aquatic plant species (duckweed and water hyacinth) and climatic parameters.

Effect of Aeration on Nutrient Removal Performance of Oxidation Ditch Systems
Environmental Engineering Science, 2005This paper evaluates the mechanism of nutrient removal in an oxidation ditch system using basic process stoichiometry and model simulation. Aeration intensity and the resulting dissolved oxygen concentration are identified as the main parameters defining the denitrification potential, and affecting the extent of nitrification/ denitrification processes,

Enhancement of nutrient removal performance of activated sludge with a novel hybrid biofilm process
Bioprocess and Biosystems Engineering, 2018The aim of this study was to investigate the efficacy of a hybrid biofilm pilot-scale treatment plant, designed with a novel configuration by the integration of a fixed-film system, to improve nitrogen removal. The pilot-scale system was established at a wastewater treatment plant in Istanbul and operated based on stream separation following a process ...

The self-organizing map (SOM) model was applied to predict outflow nutrient concentrations for integrated constructed wetlands (ICWs) treating farmyard runoff. The SOM showed that the outflow ammonia-nitrogen concentrations were strongly correlated with water temperature and salt concentrations, indicating that ammonia-nitrogen removal is effective at ...

In this paper, the performances of Fixed Bed (FXB), Fluidized Bed (FLB), and Hybrid (HYB, i.e. fluidized bed followed by fixed) operational conditions of biofilm reactors were investigated. The COD (chemical oxygen demand), TN (total nitrogen) and TP (total phosphorus) were taken as performance-indicator parameters.
